Brown bleeding 8 weeks post c-section?

So a couple of days ago I woke up in the night in pain from my c-section area and I noticed I was in a full out stretch. I guess I stretched too hard in my sleep and pulled something inside? I had a lot of burning type pain afterwards that lasted about half hour and I fell back asleep. It’s still a little sensitive now if I do anything too strenuous but nothing to crazy. The only thing that worries me is I have been having quite a bit of menstrual cramping ever since and have been bleeding quite a bit of brown blood. I was bleeding all day yesterday (more like light flow period) and thought it was bc I disturbed some healing and it was just some residual blood from it. I’m now on day 2 and still bleeding without it looking like it’s letting up and it’s still very brown. Should I be concerned and get checked out? I feel fine otherwise.
